The Diagrams section, beginning on page 7-1, includes a block diagram and an interconnect diagram. A12 Main Board The A12 Main board consists of the following blocks: PCI Interface The PCI interface consists of a PCI target and a PCI master. The PCI target has three base address register areas. The PCI master has two DMA controllers used to transfer data from the A12 Main board to the system memory or from the system memory to the A12 Main board. Mega FIFO The Mega FIFO has 32 MB for playing and 32 MB for recording a stream data. It consists of two 256 megabit synchronous DRAM and FPGA. This FIFO is used to compensate for non-realtime operation of Windows XP. TS Controller The TS controller consists of the following blocks: TS Packet Type Controller. This controller sets a packet size of 188, 204, 208, and Non TS (free length) as a TS packet type. For a Non TS format, the controller also sets a packet length (16-255) and data length (16-255). The data length shows an effective data length in one TS packet. Data Valid Controller. This block generates a data valid signal that synchronizes with the first byte of a TS packet when stream output is started. Psync Controller. Psync is a signal to identify the sync byte in a transport stream. When the controller is not in the Psync Regeneration mode, Psync is recognized as the first byte of a transport stream. In this case, Psync is output in the constant interval even when the sync byte is rewritten in the value except for 47h. For the Super Frame mode, Psync is output only once in 384 packets. Psync Regenerator. This block becomes active when the Psync Regeneration mode is set. The block detects the sync byte (47h) in a data stream and regenerates a Psync signal. The psync generator supports 188, 204, 208 TS packets only. RTX100B ISDB-T RF Signal Generator Service Manual 2-1 Theory of Operation PCR/DTS Updater. This block consists of a PCR counter and update logic. The PCR counter is a complex counter, which consists of a 9-bit counter (range 0-299) and 33-bit counter. The counter counts the 27 MHz standard frequency. The update logic replaces the PCR and PTS/DTS values in a transport stream with the sum of the original value and the PCR counter value. Receive Rate Counter. This 24-bit counter is used for receive-rate calculation on recording process. When using a data valid signal (DVALID), the counter counts byte data rate. When not using DVALID, the counter counts receive clock. Transmit Byte Counter. This 32-bit counter counts transmitted bytes. This counter can be read by the control software. 2-2 Interrupt Controller The interrupt controller sends the following interruption signals to the CPU: Play FIFO empty, Record FIFO full, external trigger, 10 Hz, Playout DMA transfer finished, and Record DMA transfer finished. These interruptions can be disabled by the RTX100B application software. At power on, all interruptions are disabled. TS Clock Generator The TS clock generator consists of a VCO (Voltage Control Oscillator), phase detector, frequency divider. The VCO is used for generating a TS clock, and it covers frequencies of 400 MHz to 800 MHz. The frequency divider divides the clock by 65536 to 1. Reference Clocks The reference clocks consist of 27 MHz TCXO and half-divided output of 54 MHz clock generator. These clocks are used to compare the frequency of the TS Clock Generator. RTX100B ISDB-T RF Signal Generator Service Manual Theory of Operation A20 PCI Backplane Board The A20 PCI Backplane board consists of the following connectors and circuitries: PCI and ISA Connectors ATX Power Control Circuit Interconnect Circuit Fan Speed Control Circuit IEEE1394b Interface The J100, J110, and J120 connectors are PCI slots for 5 V. The J130 connector is a PCI slot for 3.3 V and is reserved in the future. The J100 connector is the system slot and is used to install the CPU board (single board computer: SBC). The J110 and J120 connectors are used to install the A12 Main board and the A150 ISDB-T RF Output board. The PWR_Button line (Pins 9 and 10 of J310) of the SBC is connected to the power switch on the Keypad board through the Front-Panel Processor board. When the power switch is pressed, the SBC causes the PSON# signal to go low. When the PSON# signal becomes low, Q10 turns on and +12 V main power is also on. When the power switch is pressed again, its status is sent to BIOS and the PSON# signal turns high. This circuit includes a +12 V to +5 V DC-DC converter, a +12 V to +3.3 V converter, and a +12 V to --12 V converter. There are four connectors in the interconnect circuit: J230, J240, J290, and J310. J230 is used to connect the board to the LCD interface on the CPU board. J290 is used to connect the board to COM2 on the CPU board. J310 is used to connect the board to the hard disk drive LED and reset/power button on the CPU board. J240 is used to connect the board to the Front-Panel Processor board. This circuit also has an RS-232C level converter. U700 (PIC Micro) controls the internal fan revolution. It gets the temperature data from the sensors (U720 and U730) through 12C BUS and controls the supply voltage to the fan (7 V to 11.5 V). The IEEE1394 interface consists of the 1394b link-layer device (U110), cable transcriver/arbiter (U120), oscillator (Y100), serial EEPROM (U140), regulators (U130 and U230), and IEEE1394b connector (J140). RTX100B ISDB-T RF Signal Generator Service Manual 2-3 Theory of Operation A150 ISDB-T RF Output Board The A150 ASI ISDB-T RF Output board consists of the following blocks: Local Bus Interface The local bus interface communicates with the A12 Main board. There are two sets of 16-bit signal lines for Rx and Tx: 8-bit data lines for single-end connection, 4-bit control lines for single-end connection, and 4-bit control lines for differential connection. These lines are connected to the A12 Main board in one-on-one. ASI RX and ASI Decoder This block changes an ASI signal received from the ASI In connector into parallel transport stream data. ASI Encoder and ASI TX This block changes parallel transport stream data into an ASI signal and output the signal. PCI Interface FPGA Channel Coding FPGA OFDM Modulation FPGA 2-4 This block consists of an FPGA of ALTERA. It is the interface for PCI and interchange of an incoming transport stream signal. It also generates an interrupt signal when an IIP of a transport stream is decoded and Mode is changed. This block performs coding of ISDB-T. It has four synchronous SRAMs as buffers for interleaving. This block performs OFDM modulation using IFFT. Digital PLL FPGA This is a digitally controlled PLL, which synchronizes the reference clock (VCXO) with an internal reference clock or an external clock. This block has a feature to pass the U600 output to U1100. RF DAC This block converts OFDM modulated data to an analog signal. It has an oversampling circuit and digital filter for reducing spurious events. The block also has two A/D converters for I and Q signals. RF Carrier Synthesizer This block generates a carrier signal for the RF output. It directly generates a career frequency of UHF. Quadrature Modulator This block performs I/Q modulation to a carrier signal from the A/D converter output. RTX100B ISDB-T RF Signal Generator Service Manual Theory of Operation RF Matching Attenuator This block steps down an RF output level to the antenna input level of a receiver and matches the impedance with 75 Ω. Front-Panel Processor Board The Front-Panel Processor board consists of the following circuitries and connectors: Front-panel Keypad Interface and LED Control LVDS Data for LCD The state of the front-panel keys are read by the one chip processor on the board and any setting changes are reported to the SBC through the COM2. The processor also controls the LED on/off state of the front-panel LEDs. The LVDS data from the SBC is routed through the board to the LCD. Backlight Power Control When the Window OS puts the instrument into power saver mode, the LVDS data from the SBC stops and the LCD backlight needs to be turned off or a rainbow display will occur. When the LVDS data stops, the common mode voltage of the data lines changes from the normal + 1.25 V to 0 V. The comparator U10 senses this voltage change and turns off the power MOSFET switch Q10 and the power to the backlight inverter board. LCD Brightness Control The potentiometer R301 could be used to dim the LCD backlight brightness. But R302 is not installed, so the adjustment has no effect and the backlight is at maximum brightness. USB Ports There are two USB connectors on the board that are connected through a cable to the USB 2.0 interface connector on the CPU board. Keypad Board The Keypad board contains the switch patterns for the elastomer keys and the front-panel LEDs. The board is connected to the Front-Panel Processor board by the board-to-board connectors J10 and J11. A40 AC Distributor Board The A40 AC Distributor board supplies standby power (5VSB) to the SBC and the ATX power control circuit on the A20 Backplane board.

It also describes how to clean the exterior and interior of the RTX100B. Inspection and cleaning are done as preventive maintenance. Preventive maintenance, when done regularly, may prevent the RTX100B from malfunctioning and enhance its reliability. Preventive maintenance consists of visually inspecting and cleaning the RTX100B and using general care when operating it. How often preventative maintenance should be performed depends on the severity of the environment in which the RTX100B is used. A proper time to perform preventive maintenance is just before the RTX100B adjustment. General Care The cabinet helps keep dust out of the RTX100B, and is needed to meet EMI and cooling requirements. The cabinet should be in place when operating the RTX100B. The front cover protects the front panel and display from dust and damage. Install the front cover when storing or transporting the RTX100B. Inspection and Cleaning Procedures Inspect and clean the RTX100B as often as operating conditions require. The collection of dirt on components inside can cause them to overheat and break down. (Dirt acts like an insulating blanket, preventing efficient heat dissipation.) Dirt also provides an electrical conduction path that could cause an RTX100B failure, especially under high-humidity conditions. CAUTION. Avoid the use of chemical cleaning agents that might damage the plastics used in this RTX100B. Use only deionized water when cleaning the menu buttons or front-panel buttons. Use an ethyl alcohol solution as a cleaner and rinse with deionized water. Inspection — Exterior. Inspect the outside of the RTX100B for damage, wear, and missing parts, using Table 5-1 as a guide. An RTX100B that appears to have been dropped or otherwise abused should be checked thoroughly to verify correct operation and performance. Immediately repair defects that could cause personal injury or lead to further damage to the RTX100B.

RTX100B ISDB-T RF Signal Generator Service Manual Repair action 5-5 Maintenance Cleaning Procedure — Interior. To clean the RTX100B interior, perform the following steps: 1. Blow off dust with dry, low-pressure, deionized air (approximately 9 psi). 2. Remove any remaining dust with a lint-free cloth dampened in ethyl alcohol and rinse with warm deionized water. (A cotton-tipped applicator is useful for cleaning in narrow spaces and on circuit boards.) STOP. If, after performing steps 1 and 2, a module is clean upon inspection, skip the remaining steps. 3. If steps 1 and 2 do not remove all the dust or dirt, the RTX100B may be spray washed using a solution of ethyl alcohol by performing steps 4 through 8. 4. Gain access to the parts to be cleaned by removing easily accessible shields and panels (see Removal and Installation Procedures). 5. Spray wash dirty parts with the ethyl alcohol and wait 60 seconds for the majority of the alcohol to evaporate. 6. Use hot (120 _F to 140 _F) deionized water to thoroughly rinse them. 7. Dry all parts with low-pressure, deionized air. 8. Dry all components and assemblies in an oven or drying compartment using low-temperature (125 _F to 150 _F) circulating air. Lubrication.
